I would recommend searching for your topic in Google Scholar before starting a general Google search. Google Scholar only returns items from academic sources, increasing your chances of finding articles that you can cite.
Add phrasing or subjects to help narrow your search results. Some examples:
Is online education effective?
online classes vs. traditional classes
constant news exposure and fear
Add the following words to help you find data and studies to support your research:
+ research
+ case studies
In a general Google search, you can add a site limiter to only pull page results from educational institutions (site:.edu):
headline stress disorder site:.edu
